What you put is correct because two negatives make a positive so it would be 5 + 7 making it the greatest value
Answer: 12
Step-by-step explanation:
Given the function :
f(x),
x is defined as the number of questions answered correctly in a certain section.
Thus given that the function; f(12) = 18 means a test-taker receives 18 points for answering x questions in the section correctly
The number of correct questions will be :
Compare ;
f(x) = f(12)
Hence ; x = 12 = number of questions answered correctly in the section.
Answer:
is the simple form of 0.35.
i.e.
![0.35\:=\frac{7}{20}](https://tex.z-dn.net/?f=0.35%5C%3A%3D%5Cfrac%7B7%7D%7B20%7D)
Step-by-step explanation:
Considering the decimal number
![0.35\:\:](https://tex.z-dn.net/?f=0.35%5C%3A%5C%3A)
First lets convert it into a fraction
![0.35\:\:](https://tex.z-dn.net/?f=0.35%5C%3A%5C%3A)
Multiply and divide by 10 for every number after the decimal point.
There are two digits to the right of the decimal point, therefore multiply and divide by 100.
![=\frac{0.35\cdot \:100}{100}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B0.35%5Ccdot%20%5C%3A100%7D%7B100%7D)
![=\frac{35}{100}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B35%7D%7B100%7D)
Now reduce the fraction
into a simple form

![\frac{35}{100}=\frac{5\cdot \:\:7}{5\cdot \:\:20}](https://tex.z-dn.net/?f=%5Cfrac%7B35%7D%7B100%7D%3D%5Cfrac%7B5%5Ccdot%20%5C%3A%5C%3A7%7D%7B5%5Ccdot%20%5C%3A%5C%3A20%7D)
![=\frac{5\cdot \:7}{5\cdot \:20}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%5Ccdot%20%5C%3A7%7D%7B5%5Ccdot%20%5C%3A20%7D)

![=\frac{7}{20}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B7%7D%7B20%7D)
so
![\frac{35}{100}=\frac{7}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B35%7D%7B100%7D%3D%5Cfrac%7B7%7D%7B20%7D)
Therefore,
is the simple form of 0.35.
i.e.
![0.35\:=\frac{7}{20}](https://tex.z-dn.net/?f=0.35%5C%3A%3D%5Cfrac%7B7%7D%7B20%7D)
